An ActiveX control can be very well a non-visual (non UI) component.

> These files have an OCX extension and can be hosted by any ActiveX Container. VFP, VB, IE, Office Apps, Visio, etc are all capable of hosting an OCX Control.

But the ocx file is in fact a dll inside, isn't it?

>Does this clarify things???

Yes and no. Is the difference just a naming difference or are there any differences between the interfaces supported, etc. The more I read about ActiveX/COM/OLE/etc, the less I understand where's the difference between ActiveX and COM. Is there any?
